Charging The Battery; Inserting And Removing The Battery - Bosch Drive Unit BDU3740 Originalbetriebsanleitung

Charging the battery

A Bosch eBike battery must only be charged using an
u
original Bosch eBike charger.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using it for the first time.
To charge the battery, read and follow the instructions in the
operating manual for the charger.
The battery can be charged at any state of charge. Interrupt-
ing the charging process does not damage the battery.
The battery has a temperature monitoring function which
only allows it to be charged within a temperature range of
0 °C to 40 °C.
Do not reconnect the battery to the charger until it has
reached the correct charging temperature.
Battery charge indicator
The five LEDs on the battery charge indicator (6) indicate
the battery's state of charge when the battery is switched
on.
Each LED represents approximately 20% of the charging ca-
pacity. When the battery is fully charged, all five LEDs will be
lit.
The battery's state of charge when switched on is also shown
on the display of the on-board computer. Read and follow
the instructions in the operating manuals for the drive unit
and on-board computer.
If the battery capacity is less than 10%, the last remaining
LED will flash.
If the battery capacity is less than 5%, all the LEDs on the
battery charge indicator (6) on the battery will go out. The
display function of the on-board computer, however, will
carry on working.
Once charging is complete, disconnect the battery from the
charger and the charger from the mains.

Inserting and removing the battery

Always switch off the battery and the eBike system
u
when inserting the battery into the holder or remov-
ing it from the holder.

Bosch eBike Systems
If the temperature of the bat-
tery is outside this charging
range, three of the LEDs on
the battery charge indicator
(6) will flash. Disconnect the
battery from the charger and
let it acclimatise.
Note: As a result of varying designs, the battery may need
to be inserted and removed using a different method. Read
the operating instructions of the eBike manufacturer.
Inserting the PowerTube battery (pivot) (see figure B)
In order for the battery to be inserted, the key (1) must be
inserted into the lock (2) and the lock must be open.
❶ To insert the PowerTube battery (4), place it so that its
contacts are in the lower holder of the frame.
❷ Push the battery upwards until it is held by the safety
restraint (8).
❸ Hold the lock open with the key and press the battery
upwards until you hear it click into place. Check that
the battery is secure in all directions.
❹ Always secure the battery by closing the lock (2) –
otherwise the lock may open and the battery may fall
